What tach did you get?
Brand, model number.
Happy Racing!

The odds of having purchased two separate defective tachs is about zero.
Without the model number we cannot provide exact details.
However many tachs have a:
GROUND
ILLUMINATION TERMINAL
TACH TERMINAL
12 VOLTS IN TERMINAL
We suggest you have a friend give you some in person assistance.
Also, you might want to buy one from a speed shop.
It might cost more, but there are people there that “turn the wrenches” and should be able to point out what wires go where.
You don’t want to hook it up wrong because you might damage it.
Happy Racing!

Re: wiring up my tach
Some tachs require you to use the GM filter that should be hidden in your dash.

Re: wiring up my tach

Re: Filter.
As long as you hooked up the wire the used to go the original tach you are using the appropriate wire.
You want a direct feed from the TACH TERM which originates near the distributor.

Re: wiring up my tach
i hooked mine up to the radio fuse, a ground to the firewall, and the wire on the "tach" part of the distributer and mine works fine. i have a "equus" from o'reillys. its a 3 3/8 in dash tach. it cost 70 bucks.

Re: wiring up my tach
Every tach I`ve wired up on my camaro or chevy truck has had ground,power wire for light and a wire that connects to the tach lead at the coil.Pretty simple and I`m no mechanic.Ive never needed a filter.
